SEALING TOOL OR CHUCK FOR BOTTLES.

Specification of Letters I'atent.

Patented sept. 29, 1914.

Application filed August30, 1911. Serial No. 646,945.

To all whom it may concern:

lie it known that I, GUSTAVE LIDSEEN, a citizen of the United States, and a resident .of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sealing Tools or Chucks for Bottles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accomianvin" drawin s and to the numbers of u I: b

reference marked thereon, which form a part of this specification.

It has become general in many communities, and in practically all large centers of distribution of milk and the, like, to furnish what is termed certified milk to such consumers who may require the same, and particularly for the use of infants, invalids and others whose health or preference require milk as free as possible from bacteria and contamination.

In the past, it has frequently occurred that, upon test, milk sold as certified or p11 re milk, when examined in the laboratory,

has sometimes been very impure, 'indicatin that the contents of the bottle had been tampered with, or perhaps the bottle refilled. This has heretofore been quite possible, inasmuch as the bottle closures used on such bottles have usually been capable of repeated use, thereby permitting impure milk to be fraudulently sold. It is also true of some of the other closures used for certified milk bottles, that such closures do not prevent the milk from becoming contaminated during transit or after inspection.

The object of this invention is to afford a sealing device or chuck whereby a suitable sealing cap may be applied to milk bottles and the like, in such a manner, as to effectually seal the same from contamination and in such a manner as to necessitate the destruction or such injury of the sealing cap when removed as to preclude its second use.

It is a further object ofthe invention to afford asealing tool or chuck adapted to be manually applied in securing the sealing cap upon the bottle, and incapable of injuring or cracking the bottle in applying the seal.

it is also an object of the invention to afford a sealing device of the class described,

in which, although the seal is rigidly secured upon the bottle, the pressure exerted in applying the same is expended upon the seal and not upon the bottle, in consequence protecting the bottle from injury.

It is also an object of the invention to afford a construction adapted for rapid use thus econoi'nizing greatly in the time heretofore required in sealing such bottles.

It is a further object of the invention to afford a' construction in which the seal is effected manually by the operator, and whereby the operator may readily determine in each instance, the efficiency with-which the seal was applied by the operation of the tool.

A preferred embodiment of the invention is hereinafter more fully illustrated and described.

In the drawings: Figure 1 is a side elevation of a device embodying my invention. Fig. 2 is a central, longitudinal section thereof, showing the same in position preparatory to sealing. Fig. 3 is a similar View with the cap sealed. in place. Fig. 4 is an enlarged section on line 44 of Fig. Fig. 5 is an enlarged fragmentary section taken on line 55 of Fig. 1. Fig. 6 is an enlarged fragmentary section illustrating the spring engagement of the yielding chuck jaws. Fig. 7 is a bottom plan .view of the sealing tool or chuck. Fig. 8 is an enlarged transverse section taken through the chuck 'at one of the springs, and showing the same in elevation. Fig. 9 ista detail illustrating a construction in which an integral forming lip is provided on each chuck member.

Fig. 10 is .a section taken below the sealing cap on a milk bottle, and illustrating the seal shown in Figs. 3 and 8. Fig. 11 is a similar View and illustrating the seal afforded when a jaw such as illustrated in Fig. 9, is used inthe tool.

As shown in the drawings: The sealing tool comprises levers 1 and 2, articulated or hinged together at their meetingends and there each enlarged laterally to afford a semi-circular head of considerably larger diameter than the exterior diameter of the bottle mouth to which the seals are .to be applied. Integrally connected with each of said heads and extending downwardly therefrom, is a peripheral flange 3, on each, together affording the lateral retaining walls for the chuck jaws 4, as shown two in number, and semi-circular in form, and

are springs 6, as shown in Figs. 2, 3, 6,-and

8, and in, dotted lines in Fig. 7. Said-chuck jaws are provided (in the constructions illustrated in Figs. 2', 8, 7 and 8) with closely arranged apertures, disposed near the lower edge thereof, and extending therethrough and threaded, or otherwise rigidly engaged therein are pins or bolts, the inwardly projecting heads 7, of which are peripherally-cbncaved to afiiord a shallow,

peripheral groove, adapted to engage beneath the edge or apron of the sealing cap to turn the same upwardly, as indicated in Figs. 3 and 8, when the jaws are closed.

Extending downwardly on each side of each handle or lever 1 and 2, andadjacent the head, are parallel flanges 8, and pivotally engaged thereon adjacent the chuck jaws, is a lever 9, having a yoked head 10, shown-in Fig. 7, adapted to fit loosely around the bottle neck, and engaging beneath the chuck jaws respectively. Pivotally engaged between said flanges 8, near'the outerend thereof, is a bent lever, one end 11, of which extends outwardly beneath thellevers 1 and 2, and is adapted to be engaged by the hands, and the other (and shorter) end of which extends inwardly between said flanges and is pivotally connected with the end of the lever 9, by means of a link 12, aifording a toggled connection. Extending through each of the levers 1,- and provided with a set nut 13, thereon, is an adjusting screw 14, whereby the throwof the toggle lever, in actuating the chuck jaws with the hands, may be readily adjusted.

The operation is as follows: The bottle 15, having the usual outwardly rounded head or lip 16, thereon, is closed, if desired, by first placing paratfined paper 17, on the 1 interior shoulder. A second sealing closure 18, either of parafiined paper or any suitable material, for example, a rubber ring or sheet 18, if desired, is then-placed upon the bead, and a metallic sealing cap 19, usually of thin tinned soft steel, and having an apron 1 or margin sufliciently wide toextend well below the bead 16, and fitting closely therearound, is applied over the mouth of the bottle, as shown in Fig. 2. The sealing tool is then placed over the same, as shown in Fig. 2. This can easily be accomplished, inasmuch as the tool is hinged in halves, and the head readily opens to receive the mouth of the bottle therein.

When in theposition shown in Fig. 2, the operator pressing downwardly upon the levers 1 and 2, grips the levers 11, upwardly with the hands, thereby throwing the inner yoked ends 10, ofthe levers 9, upwardly and carrying the sealing jaws 4, upwardly against the tension of their springs, and rolling the free edge or apronof the sealing 'cap inwardly and upwardly, as shown in Figs. 3 and 8, and crushing the-same firmly a ainst the under side of the bead. Each of theheads 7 on the sealing jaws indents the margin of the cap, giving the same a characteristic fiuted appearance on the under side, as illustrated in Fig. 10, and so firmly engaging. the same in place that considerable mutilation of the seal is necessary before the same can be removed.

As shown, the central portion ofthe sealing cap is depressed somewhat, as shown in Fig. 8. This permits theapplication of any distinguishing trade-mark, character or other indications thereon without danger of injury or mutilation thereof when applied to the bottle.

If desired, the jaws may be constructed as illustrated in Fig. 9, in which, in lieu of the pins 7, used, to afford a fluted appearance of the under portion of the seal, a permanent and integral sealing lip 20, is secured on the under side of each of the chuck jaws, and is ;concaved on its upper side or that engaging the margin of the seal and acts to roll the sealing margin upwardly and inwardly around the bead of the bottle to close the same uniformly and tightly therebeneath, as illustrated in the seal 21, shown in Fig. 11.

Of course, it is to be understood that sealing jaws equipped either with the pin 7,

or with the sealing lip 20, may be used, as preferred, and it is to be understood also that any suitable materials may be used beneath, or in conjunction with the sealing caps, as may be preferred. I have shown but one (and that a preferred) embodiment the apronof the cap inwardly and upwardly into engagement with the bottle. I
